The aftershock of a stellar explosion rippling through space is captured in this new view of the supernova remnant called W44. The image combines longer-wavelength infrared and X-ray light captured by the European Space Agency's Herschel and XMM-Newton space observatories.

NASA also plays an important role in the Herschel mission, with the U.S project office based at the agency's Jet Propulsion Laboratory in Pasadena, Calif.

W44 is located about 10,000 light-years away, within a forest of dense star-forming clouds in the constellation of Aquila, the Eagle. It is one of the best examples of a supernova remnant interacting with its parent cloud.

The supernova remnant is the result of a massive star that reached the end of its life and expelled its outer layers in a dramatic explosion. All that remains of the stellar behemoth is the spinning core of a neutron star, or pulsar.

Identified as PSR B1853+01, the pulsar is the bright point to the top left in W44, colored light blue in this image. It is thought to be around 20,000 years old. Like all pulsars, as it rapidly rotates, it sweeps out a wind of highly energetic particles and beams of light ranging from radio to X-ray energies. The center of the supernova remnant is also bright in X-rays, coming from the hot gas that fills the shell at temperatures of several million degrees.

Herschel's infrared eyes seek out regions of gently heated gas and dust farther from W44, where new stars are congregating. Examples include the arrowhead-shaped star-formation region to the right of W44, which appears to point to another trio of intricate clouds further to the right and above.

More broadly, a number of compact objects scattered across the scene map the cold seeds of future stars that will eventually emerge from their dusty cocoons.

Finally, diffuse purple emission towards the bottom left of the image provides a glimpse of the plane of our Milky Way galaxy.

Herschel is a European Space Agency cornerstone mission, with science instruments provided by consortia of European institutes and with important participation by NASA. NASA's Herschel Project Office is based at JPL, which contributed mission-enabling technology for two of Herschel's three science instruments. The NASA Herschel Science Center, part of the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena, supports the United States astronomical community. Caltech manages JPL for NASA.
